My laptop started shutting off on 60% battery charge, no warning. Ran a battery report: capacity down to 27 (was 55).
I tried to take out battery and run laptop on AC alone, but no option; it will only work when battery is in.
Since yesterday the orange charger light is flashing on AC and though battery is fully charged, the laptop turns off as soon as I take it off AC. Laptop won't run on battery alone.
Tried the battery reset button, did the F2/F9/F10 (which meant laptop would not boot, could not find a device), and tried uninstalling the battery-Microsoft APCI-adapter and reinstalling it.
But light is still blinking and laptop still not running on battery.
Any ideas if it is the battery that needs replacing or another hardware issue?
